// Java Program to Copy Elements from
// One PriorityQueue to Another
import java.util.PriorityQueue;

// Main Class
public class Main {
    public static void main(String[] args) {
        // Creating  priority queue of integers
        PriorityQueue<Integer> sourcePq = new PriorityQueue<>();
        
        // Creating another priority queue to copy
          // elements from the original priorityQueue
        PriorityQueue<Integer> destinationPq = new PriorityQueue<>();
        
        // Adding elements to the original priority queue
        sourcePq.add(1);
        sourcePq.add(2);
        sourcePq.add(3);
        sourcePq.add(4);
        sourcePq.add(5);
        
        // Copying elements from source priorityQueue to it's copy
        destinationPq.addAll(sourcePq);
        
        // Printing the elements of the original priority queue
        System.out.println("Original Priority Queue: " + destinationPq);
        
        // Printing the elements of the copied priority queue
        System.out.println("Copied Priority Queue: " + destinationPq);
    }
